Technological objectives

The Technological objectives of BIOMAN are:

* To increase the biogas yield from manure fibres and straw from
50% to at least 70% of the theoretical potential through a
combination of technologies (separator units, re-injection of
recalcitrant fraction, ultrasound and enzyme treatment), when
applied together will increase the digestibility of the separated
fibre fraction and hence the overall biogas potential

* To test the viable Re-Injection Loop concept in a large-scale
reactor at a cost less than the running costs of the Re-Injection
Loop. Economic breakeven is difficult to calculate but is estimated
to approx. 4-8 percentage points additional gas output, relative to
theoretical max.

* To implement the Re-Injection Loop strategy/concept in a
large-scale facility
